Area Forecast Discussion National Weather Service Honolulu HI 845 PM HST Wed Jan 22 2020

SYNOPSIS. Variable winds in a stable land and sea breeze weather pattern will continue over most of the islands through Friday afternoon. Expect low clouds developing with isolated light interior showers possible each afternoon followed by overnight clearing across most islands. One exception will occur over the southeast slopes of the Big Island where a slight increase in clouds and showers remains in the forecast through Friday. A weak front stalling near Kauai on Friday afternoon will increase clouds and showers over the Garden Isle through Saturday. Moderate trade winds will return from Friday afternoon through the weekend along with slight increases to windward and mountain showers. Winds will decrease and veer southeasterly in a dry land and sea breeze pattern for the first half of next week.

DISCUSSION. The weather picture this evening shows the Hawaiian Islands under the southwestern edge of the subtropical ridge with frontal boundary north of the islands heading east, and another cold front approaching the state from the northwest direction. Dry and stable weather conditions under the ridge are forecast with variable winds allowing local scale land and sea breezes to develop over most islands through Friday. Dry moisture levels in the atmosphere will produce cooler than normal low temperatures each night.

Friday through Sunday, the weather pattern changes a bit as a weakening cold front moves into Kauai and Niihau. This front will reach Kauai by Friday afternoon just as the forward motion along the frontal band stalls out. Expect increasing clouds and showers for both islands from Friday into Saturday. Trade winds will bleed out ahead of the stalling frontal band with trades slowly spreading eastward to all islands through Saturday morning. Clouds and isolated to scattered showers over windward and mauka areas will also return with these moderate trades lasting through the weekend. East to southeast trade winds on Sunday will push the clouds and showers along the frontal boundary towards the northwest away from Kauai County with improving weather conditions in the forecast from Saturday night onward.

Monday through Wednesday, trade winds will veer towards the southeast direction with a subtropical ridge axis anchored roughly 400 miles north of the island chain. Light southeasterly winds will allow a return to land and sea breezes over the islands with a slight increase to clouds and showers along the southeastern slopes of the Big Island. This drier weather pattern will bring sunny skies back to the islands through the middle of next week. Additional high clouds moving into the region next week will improve sunrise and sunset colors from Wednesday onward.

AVIATION. A high pressure ridge will remain over the state for the next 24 hours and allow for a light and variable wind pattern. Relatively dry air in place should keep precipitation chances low. By Thursday afternoon, expect weak sea breeze development along coastal areas. Otherwise, light variable winds and dry conditions will prevail once again.

MARINE. Light and variable winds will continue through early Friday, then shift out of the north to northeast and increase into the moderate to fresh category late Friday as a front passes north of the area. Fresh to locally strong easterly trades are expected for a brief period over the weekend before trending back down by early next week as a series of fronts pass to the north. Although seas may briefly drop below the Small Craft Advisory (SCA) level (10 ft) Thursday night through Friday as the large northwest swell subsides, advisory- level conditions will return Friday night through the weekend due to a combination of winds and seas.

Surf along north and west facing shores will remain up through next week due a series of large northwest swells evolving from the progressive pattern over the northern Pacific. The current swell building down the island chain has peaked at the northwest offshore buoys (15 ft 17 sec) this afternoon, which will correspond to an overnight peak locally. Although a gradual downward trend will begin through the day Thursday, surf will hold above warning levels for exposed north and west facing shores. The downward trend will be short-lived due to another large northwest swell arriving Friday night into Saturday from a large area of gale- to storm-force winds that has setup within the 300-320 directional band relative to the islands over the northwest Pacific. Surf will respond and return warning levels Saturday through Sunday. As this swell eases into early next week, advisory-level surf may hold through late Monday. Another large northwest swell will be possible by next Wednesday as a gale develops over the far northwest Pacific this weekend.

Surf along exposed east facing shores will remain small through the period due to the lack of persistent trades locally and upstream across the eastern Pacific.

Surf along south facing shores will remain small through next week. A couple of background south swells expected over the weekend and next Tuesday should be enough to keep things from going flat.

HFO WATCHES/WARNINGS/ADVISORIES. High Surf Warning until 6 PM HST Thursday for Niihau-Kauai Windward-Kauai Leeward-Waianae Coast-Oahu North Shore-Oahu Koolau-Olomana-Molokai-Maui Windward West-Maui Central Valley- Windward Haleakala-Kona-Kohala.

Small Craft Advisory until 6 PM HST Thursday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters-Kauai Channel- Oahu Windward Waters-Oahu Leeward Waters-Kaiwi Channel-Maui County Windward Waters-Big Island Windward Waters-Big Island Leeward Waters-Big Island Southeast Waters.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
